I tried a simple three line hello world program, which tries to get
the SID for Unix_User+1:
bash -c 'getent passwd "Unix_User+1"'
Unix_User+1:*:4278190081:4278190081:U-Unix_User\1,S-1-22-1-1:/:/sbin/nologin
But putting "S-1-22-1-1" into ConvertStringSidToSidA("S-1-22-1-1",
&sid) fails with ERROR_INVALID_SID on Cygwin.
Why? I thought SMB had "S-1-22-1-*" reserved for its usage, and Cygwin
uses Unix_User+1 in it's output.
How can I get ConvertStringSidToSidA("S-1-22-1-1", &sid) working in my program?
Cygwin's focus is on using POSIX tools to do useful work on Windows hosts,
avoiding the native APIs and tools because of their innumerable shortcomings.
You should ask these Windows queations on more appropriate forums, such as MS,
Mingw64, Msys2, or SO:
https://stackoverflow.com/questions/54894967/why-does-convertstringsidtosid-fail-to-convert-a-string-sid
after carefully reading the MS docs:
https://learn.microsoft.com/en-us/windows/win32/api/sddl/nf-sddl-convertstringsidtosida
and use a (re-/)search tool to find this basic background information and
answers to queries, not ask on Cygwin lists.
